COMPACT CONCENTRATOR OF EFFLUENTS AND GAS-FLUSHING UNIT FOR REMOVAL OF CONTAMINANTS Russian patent published in 2015 - IPC C02F1/04 

FIELD: process engineering.

SUBSTANCE: proposed concentrator comprises gas inlet pipe, gas discharge outlet and flow channel communicating gas inlet pipe and gas discharge outlet. Note here that flow channel comprises contracted section to increase has flow rate therein. Fluid inlet pipe injects fluid in gas flow upstream of contracted section so that gas-fluid mix is completely mixed in flow section to cause the fluid partial evaporation. Mist separator or gas flushing unit downstream of contracted section removes trapped fluid drops from gas flow to return collected fluid into fluid inlet pipe via circulation circuit. Fresh fluid fed for concentration is forced into circulation circuit at the rate sufficient for compensation for fluid evaporated in said flow section.

EFFECT: concentrator can readily be connected to waste heat sources for concentration of fluid.
